How a raindrops formed?

Question

thank you for repling my question..... xD

Answer 1

Rain drops form when air containing water vapor is cooled to the dew point (the temperature when the relative humidity reaches saturation) and the air is lifted vertically in the atmosphere above the lifting condensation level (the altitude where condensation occurs) in the presence of condensation nuclei (small solid particles such as dust). The water vapor condenses on the condensation nuclei to form a water droplet. As the water droplet moves around in the air, it collides with other water droplets. The droplets get bigger and bigger until they make a rain drop. When the rain drop gets too heavy for the air to hold it up, it falls toward the Earth, hence the name rain drop.

Answer 2

Raindrop Formation

Answer 3

Clouds contain huge numbers of tiny droplets of moisture. Raindrops are formed when these tiny droplets are enlarged, first by moisture from the surrounding air condensing on them and then by coalescing with other droplets during their descent. Raindrops vary in size from about 0.02 in. (0.5 mm) to as much as 0.33 in. (8 mm) in thunderstorms. From the time they leave the bottom of the cloud, evaporation takes place and, if the cloud is high, the air warm and dry, and the raindrops small, so that they fall slowly, they may evaporate completely before they reach the earth. If they do so, the drops are called virga.

Answer 4

New research reveals that all raindrops form when water vapor below the freezing temperature crystallizes around a condensation nuclei (smoke/dust particle, outer space dust etc.) forming a single crystal snowflake. That snowflake will grow in size until too heavy to be supported by rising air currents when it will fall below the freezing level, melt, and be experienced as a raindrop.

Answer 5

Rain is formed when water vapour molecules cool down to a point where they can coalesce into a liquid again. In order to provoke said coalescence, some sort of carrier particle or binding molecule must be present as well.

Dust, smog, dirt particles are all great mediums for attracting water molecules to form a raindrop.

They don't just spontaneously turn back into water unless there's an incredible abundance of them!

Answer 6

The water in the atmosphere is in the form of an invisible gas called water vapour.Rain drops forms when warm ,humid air rises,expands and cools.This is explained below.
When the air becomes colder as mentioned above, it can not hold as much water vapour as warm air.So,condensation of water vapour starts.Water requires a non-gaseous surface to become liquid from a vapour stage.In the atmosphere,this surface presents itself as a tiny solid or liquid particles called cloud condensation nuclei.Dust particles,particles of salt,droplets of sulphuric acid,smoke etc are some of the condensation nuclei.So,water vapour condenses on these dust particles to become water droplets .Many such droplets come together to form rain drops.

There are always small particles of dust in the air, in a raincloud condensation gathers around one of these dust particles, until it becomes too heavy to stay in the air, and the raindrop will fall.

Answer 8

The sun heats up some body of water, that's when evaporation takes place. Then, that's when the water turns into a cloud, that's when condensation takes place. Once the cloud is heavy enough it starts to rain (or any other kinds of precipitation). So basically a rain drop comes from bodies of water.

Answer 9

coalescing of very small particles of water from clouds
